Michael Schumacher, Julian Bailey, Ben Collins, Chris Goodwin, Damon Hill, Russ Swift, Heikki Kovalainen, Tim Schrick, and Terry Grant have all been rumoured to be 'The Stig' but many of these have been squashed.
I bet he's someone completely random with no connection to the racing world. That would shock us all!
Who would you like it to be? Would be great if it turned out to be Jeremy Clarkson!
